Karyotypic findings showed that all cultivars were mixoploid with chromosome number ranging from 49 to 57, and 54 was the most frequent number observed.

结果表明：（1）17个栽培小菊均为混倍体，染色体数在49～57之间变异，以54条为主；（2）染色体呈现多态性：多数品种由中部、近中部和近端部着丝粒染色体组成；最长与最短染色体的比值为1.62～2.39；臂比＞2的染色体所占的比率为11.11%～29.62%；核型不对称系数为59.74%～63.37%；3个地被菊品种和'奥运橙光'、'金陵白凤'（2n=53）核型类型为&2B&，其它品种为&2A&型。

In mixoploid plants, somatic cells with 2n=25~29 were most frequent except for a few haploid cells (2n=19) and chromosome doubling cells (2n=50~60). Abnormal chromosome behaviors were observed in pollen mother cells from mixoploid BI-1 and haploid, including chromosome bridges, laggard chromosomes, meiotic cycle asynchrony and unequal separation of chromosomes.

对混倍体植株BI-1和单倍体植株的花粉母细胞(Pollen mother cells，PMCs)减数分裂染色体行为观察发现，高频率出现染色体落后、染色体桥、染色体分裂周期不同步、不均等分离等异常染色体行为。

Suspension system: it uses typical and new type suspension with the features of high strength and good impacting resistance; the load on each axle is balanced, the angle of the tie rod is designed reasonably so that it can reduce the instant frictional skidding distance between the tire and the ground during the frequent and bumping running, and can effectively reduce the tire wear, meanwhile the adjustable tie rod can adjust the wheelbase so that the partial wear and tearing wear can be avoided; the axle card is made of monobloc casting, of which the low axle card is patented product.

悬挂系统：采用独具特色的新式悬挂系统，强度高、耐冲击性强；各轴载荷平衡，系统拉杆角度设计合理，在运行频繁的颠簸过程中，减小轮胎与地面的瞬间摩擦滑移距离，有效降低轮胎磨损，同时可调拉杆可调整轴距，可有效避免轮胎的偏磨和啃胎现象；轴卡为整体铸造件，其中下轴卡为专利产品。
